I do a unit every year that guides my students through the writing of five personal paragraphs focusing on the Preterite/Passé Composé and the Imperfect Verb Tenses. I give guidelines for peer editing, self-editing, tense distinction and a rubric for grading the final copy of the writing assignment. There are twenty pages total and a table of contents to help students stay organized during the writing process. I typically give the entire packet at once, but the sections can also be given out individually.

I teach Spanish, and the concepts of preterite and imperfect combined are a struggle for many students to grasp and to learn.
I teach French: is French version for imperfect writing unit
Sorry, I put the wrong link with the French version. I updated it.
